Add network resource management API / helpers - EUCA-8499

Added NetworkingService and a GenericNetworkingService implementation
for existing network resource management functionality. The service is
accessed via the new Networking client.

RunHelpers are added to support plugging in management of additional
network resources with alternative NetworkingService implementations.

NetworkingService implementation for EDGE networking mode - EUCA-8499

Added EdgeNetworkingService which is used when the cluster controller

report EDGE networking mode when so configured.
